Hash-Based IDs vs UUID
Developers should use hash-based IDs when building systems that require secure, non-guessable identifiers, such as in APIs, user sessions, or distributed databases, to mitigate risks like ID enumeration and data leakage meets developers should use uuids when they need to generate unique identifiers across distributed systems or independent components without a central authority, such as in microservices architectures, database primary keys, or file naming. Here's our take.

UUID
Developers should use UUIDs when they need to generate unique identifiers across distributed systems or independent components without a central authority, such as in microservices architectures, database primary keys, or file naming
Pros
- +They are particularly valuable for avoiding collisions in large-scale applications, ensuring data integrity in replication scenarios, and simplifying ID generation in offline or disconnected environments
- +Related to: database-design, distributed-systems
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Hash-Based IDs if: You want they are particularly valuable in microservices architectures or when generating public-facing resource ids (e and can live with specific tradeoffs depend on your use case.
Use UUID if: You prioritize they are particularly valuable for avoiding collisions in large-scale applications, ensuring data integrity in replication scenarios, and simplifying id generation in offline or disconnected environments over what Hash-Based IDs offers.
